<BLOCKQUOTE TYPE=CITE style="BORDER-LEFT: #0000ff 2px solid; MARGIN-LEFT: 5px; MARGIN-RIGHT: 0px; PADDING-LEFT: 5px">Hmmm, so these things are actually just two way momentary switches, shorting <BR>
different contacts for either direction? I've been looking for just that to <BR>
do a simple little avionics panel for X-Plane and MSFS (too "financially <BR>
challenged"/cheap to go Hagstrom at the moment). Clicking to tune radios <BR>
drives me crazy..........<BR>

Me too, so I've uploaded some pictures of the knitter switches, as I used them. They're pretty small, so I mounted them to small PCB's to make them easier to handle. the center wire with green on it is a common ground.<BR>
<BR>
Each clockwise 'click' is a momentary close across the common ground and the left pin, a counterclockwise 'click' is a momentary close across the right pin and ground. As I said, you have top go a little slowly when making big changes, or you miss clicks.<BR>
<BR>
The radio panel is currently a little more advanced than in the pic I uploaded - I have added knobs, and across the bottom below the displays there are three more knobs - OBS1, OBS2 and HDG. That leaves me enough free inputs (the ribbon cable carries 32) for three more rotaries or six more switches. Not sure what they'll be yet.<BR>
